OIL-CONTROLLER FOR CAR-AXLES.

SPECIFIGATIONYfQr-ming part of Lettersi l atent No. 781,335, dated January 31, 1905.

Application filed June 1 1904:. Serial No. 210,637.

Be it known that I, ALBERT A. FREEMAN,

a citizen of the United States, residing at Germantown, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Oil Oontrollers for Car-Axles, &c., of which the follow-.

ing is a specification.

My lnventlon has relation to an oil-controller for supplying oil under regulation to the axles of cars or other somewhat similar appli cations of the same; and in such connection my invention relates to the general construction and arrangement of the-oil-controller for the uses defined among others.-

The nature and scope of my invention will be more fully understood from thefollowing description, taken in connection with the ac-- companying drawings, forming part hereof, in which- Figure l is alview, partly in section and partly in elevation, of an oil-reservoir and valve-actuating devices embodying main features of my invention; and Fig. 2 is a top or plan view of the spring-saddle of the controller.

Referring to the drawings, A is a reservoir of any suitable form provided with aperforated bottom a, forming a valve-seat, and with a standard a.

6 is a ball normally seated inthe perforated bottom a of the oil-reservoir A. v w

is a flat spring-metal perforated slip or saddle engaging thestem b of the ball I) and made, preferably, with curved feet cand c adapted to contact with the bottom a of the reservoir.

spring d, so that the stem of the ball-valvewill not be subject to side thrust.

The reservoir A is adapted to contain a supply of oil and is closed bya removable cap a By arranging, the spring d so as to engage the set-nuts e and the spring spanning saddle o the oil by gravity or otherwise flows d of the ball I), compensates for any lateral thrust or undue displacement of the ball seated in the perforated bottom of the oil-reservoir, due to the even distribution of pressure in the downward movement of the stem of the valve by the curved legs 0 and 0 against the bottom of thereservoir.

Having thus described the nature and object of my invention, what I claim as new, and

desire to secure by Letters Patent, is

1. An oil-controller, comprising-a reservoir provided with a perforated bottom, a ball normally adapted to close said perforation and" having a stem held in a vertical position in said reservoir, yielding means engaging said stem and adapted to'normally hold said ball against the perforation of .said bottom and to permit of the downward movement in a vertical plane of the ball-stem, substantially as and for the purposes described.

2. An oil-controller, comprisingan'oil-reservoir having a perforated bottom forming a valve-seat and a bearing, a ball provided with a stem, said ball normally seated to said bottom and the stem extending through said bearing, a saddle-spring spanning said stem and engaging said .bottom, and a spring engaging said stem and saddle, subtantially as and for the purposes described.

3. An oil-controller, comprising an oil-reservoir having a perforated'bottom forming a valve-seat, a ball provided with a partiallythreaded stem mounted in said reservoir, a saddle-spring detachably connected with said stem and bottom, a spring coiled about said stem, and means adapted to be advanced or retracted on the threaded portion of the IOO IO ing arranged so as to compensate for side thrust of the coiled spring in the movements of the ball-stem, substantially as and for the purposes described.

In testimony whereof I. have hereunto set my signature in the presence of two subscribing Witnesses.
